I have some retro noise coming from the back of my 53 Ford. I get lots of comments on my "Hi-Fi" speaker system in "Dolores"... Not quite "thumpin", but I love it. Reminds me of the good old days jamming as many as we could to get into the drive in.
I hope you don't have to slam on brakes,one of those old drive-in speakers could come sailing over the seat and knock you out! HRP
Hah! I remember being broke & buying a clapped out '66 Belair to get home from school. It had one of those duct taped under the dash. LOL
..... I remember seeing guys put their club plaques in the back window kinda tucked down between the seat top and the package tray. Always looked pretty dangerous to me.
lol.. Yeah, that would sting a little. Actually, I am planning to make a bracket to be able to screw them down in place.
